Estimating the term…
Composite adsorbent beads have a porous and non-adsorbent core comprising at least one inorganic material and a porous and adsorbent shell comprising at least one adsorbent layer comprising a porous adsorbent material on the surface of the core. The core preferably comprises agglomerated inorganic particles having a mean particle size equal to or smaller than the mean particle size of the surrounding agglomerated adsorbent particles. The beads preferably are manufactured by calcining together a non-sintered core and the adsorbent layer. The beads can be used at the outlet end of an adsorption column to improve performance.
A composite adsorbent bead for the separation of at least one gas component from a gas mixture, the adsorbent bead having at least one porous and non-adsorbent core comprising at least one inorganic material and a porous and adsorbent shell comprising at least one layer comprising a porous adsorbent material on the surface of the core, wherein the inorganic material is in the form of particles having a diameter in the range of 0.01 to 5 μm.
A process of producing composite adsorbent beads comprising forming a non-sintered core comprising an inorganic material having hydroxyl groups and an organic binder;
A dried porous and non-adsorbent core, suitable as an intermediate product for the production of a composite adsorbent bead comprising agglomerated clay particles, wherein the clay particles have a particle size in the range of 0.05 μm to 5 μm and an organic binder.
